IM PROVEIVIENT IN STOVES.

Specification forming part of Letters Patent No. 36,639, dated October14, 1862.

To all whom it may concerm Be it known that I, WILLIAM BrcKnL, ofPottsville, in the county of Schuylkill and State of Pennsylvania, haveinvented a new and useful Improvement in Fire-Boxes for Stoves andFurnaces; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which"Figure 1 is a vertical section of my invention, taken in the line :1: x,Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y,Fig. 1. Fig.3 is a section ofa portion of the same, taken in the line zz, Fig. 1.

Similar letters of reference indicate'correspending parts in the severalfigures.`

The object of this invention is to facilitate the burning of very finecoal in stoves and furnaces; andit consists in introducing air into thebody of coal in the fire-boxin such amanner as to insure a circulationof air through the entire mass and the perfect combustion of the whole.y

To enable those skilled in the art to fully understand and construct myinventionV I will proceed to describe it with reference to the drawings.Y

A represents the body or main portion of a stove,which may be ofrectangular, cylindrical, or any proper form, and B is a grate which isfitted horizontally in the lower part of the body A. This grate isconstructed of parallel bars of V form, in their transverse section, as

` shown in Fig. 1, and in the front of the body A there is placed anupright grate, C.

D represents a vertical chest or box, which may be of rectangular orother suitable form. The lower end of this chest is open and it passesthrough orinto an opening, a, in the grate B, and is supported by ahorizontal frame, E, which encompasses it and is attached to arms b,theends of which are connected to the inner sides of the body A in anyproper manner. The ehestD extends upward as high as the coal, and it isprovided with horizontal tubes F, which communicate with it and theinterior of the fire-box or body A. The tubes F are of tri-lateral formin their transverse section, and4 theirinternal diameter is cylindrical,the tubes being so placed or having such a position that an angle of twosides will be uppermost, as shown clearly in Fig. 3. rlhe outer ends ofthese tubes have a slanting oran oblique position, the upper edgesprojecting considerably beyond the lower surfaces, as shown in Fig. 1.The chest D may be provided with any suitable number of these tubes.

G represents tubes. which are attached to the inner surfaces of thesides of the body A, and project horizontally inward.

The tubes G are constructed in precisely the same way as the tubes F,and the former communicate with the external air, andare provided attheir outer ends with covers or slides H, by which the passage of airthrough them may be regulated as desired. The tubes F G are notin linewith each othcr,those,G, of the body A being in line with the centers ofthe spaces between the others F of the chest D, as shown in Fig. 2.

In the upper part of the chest D there is placed a valve, I, which issimply a rectangular bar made to fit snugly within the chest. Bylowering this bar or valve the upper tubes,y F, of the chest may be eutoff when required, asshown in Fig. 1.

From the above description it will be seen that air is admitted into thebody or mass of vcoal within thefirebox,the air passing through theash-box and up into the chest D, and out through the tubes F, and alsopassing through the tubes G into the lire-box. The inclined inner endsof the tubes F G prevent the coal from passing into the ends of thetubes and choking up the same. The arrangement is extremely simple andefficient, may be applied to either stoves or furnaces, and admits ofvery fine coal, even coal-dust, being burned with facility, as the airis admitted directly into the center of the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The employment or use of an air-chest, D, placed centrally in thefire-place, of a stove or furnace communicating with the ash-box thereofand provided with horizontal tubes F, in combination with tubes G,attached to the sides of the body of the stove or furnace andcommunicating with the external air, snbstan- 3. The triangular form ofthe tubes F G, sA tially as and for the purpose herein set forth. andthe inclined ends when used, as and for 7 2. The valve I, placed withinthe air-chest the purpose herein set forth. D, and the covers or slidesH, applied to the p XVM.
